UNDATED (AP)— Filmmakers and researchers are using drones to explore an underwater mountain in Lake Superior.
They want to see if Superior Shoal is a hotbed for aquatic life that could offer a refuge for species facing obstacles elsewhere in the Great Lakes.
The mountain sits in the middle of Lake Superior, near the boundary between Canadian and U.S. waters. The shoal is about four square miles of volcanic rock that rises up from the bottom of the lake to a height nearly three times that of the Statue of Liberty.
Researcher Michael Rennie says if Superior Shoal is a magnet for aquatic life, then maybe it could offer help for near-shore populations dealing with environmental problems.
